KIT and pulmonary fibrosis: Ding et al.26 reported about the role of SCF-c-KIT axis in bleomycin induced pulmonary fibrosis (IPF) and showed that expression of c-KIT in fibroblasts from patients with IPF was significantly higher than in those of control patients and there were more fibrosis markers, e.g. TGF-ß in the IPF group.
